sprintf / _sbrk make error

Dear ST support,

Using the nano.spec linker directive, compilation returns the error mentioned in the beginning of this post about _sbrk missing. This is seemingly due to the use of sprintf. Nevertheless, I am willing to use a sprintf function which requires no dynamic allocation (as we forbid this in a memory constraint application).

Is it possible to achieve this with the current provided glibc?
In addition, is it possible to have more information about the provided C library ?
Notably, could you provide the link to the repository holding the library source code (is it the classic glibc one found at https://www.gnu.org/software/libc/sources.html?)Question ?

Thanks for your help,
Best regards
Sylvain
